I guess i just screwed my pc

What was the program you opened that preceded the blue screen?

As for getting your accounts out, you really should've backed them up to a USB drive or similar.

However, and hopefully this will help.

1/ you need a second computer for this.
2/ you need a fully functional copy of the OS.
3/ You need to download The Ultimate Boot Cd

http://www.ultimatebootcd.com/ - Dos tools
or
http://www.ubcd4win.com/ - windows version.

Just follow the instructions and hopefully we can fix this.

final Note; There is the possibility that the BSod ( Bluescreen ) has been caused by a fault in a memory module, so it's worth getting that checked if the UBCD doesn't work.

And DO NOT wipe the HDD until you do as a replacement Ram Stick should allow the PC to boot up normal.
